This card is double-sided, 8.5" x 11" in size, UV coated, and absolutely jam-packed with information you'll need to figure out what you're doing in FileMaker Pro. The screenshot to the right shows you just how detailed this info is. The card is spill-proof, so dumping that grande Macchiato on it isn't going to harm anything.

The Functions and Operators Card for FileMaker Pro sells for $8.95 plus shipping. The website notes that a "Scripts and More Card" will soon be available as well.
